Product Description

Product Description

Product Introduction

Introducing our premium 1x7 structure unbonded prestressed steel strand, featuring dimensions of 12.7mm, 15.20mm, 15.70mm, and 17.80mm. Engineered with anti-corrosion grease and a robust sheath, this exceptional product line is specifically designed for prestigious water conservancy and hydro-power projects. With the rise in wind power installations, where tower heights extend to or surpass 120m, our steel strand is increasingly utilized for its remarkable external prestressing capabilities in concrete towers. Its impressive resistance to corrosion and fatigue significantly boosts wind resistance and extends longevity, becoming the preferred choice for industry professionals.
Our commitment to innovation shines as we adhere to the JG/T 161-2016 standards for Unbonded Prestressed Steel Strand. We have revolutionized the design to streamline the testing procedures for sheath tensile properties, making it more practical and user-friendly. This innovation ensures superior sheath performance, rigorously standardizes sheath quality, and elevates project safety standards, offering you unmatched reliability.


Product characteristics

For wind power concrete towers, our unbonded steel strand is the material of choice. Its sheath and grease thickness are tailored to meet specific technical user requirements. The sheath's surface is impeccably dense and smooth, allowing the steel strand's outline to remain visible. This precision-engineered surface quality guarantees zero air holes, mechanical damage, cracks, or noticeable wrinkles, exceeding all industry standards.
